Acoustic consulting - examining quality vs price

by Nyal Mellor October 15, 2009

Since I have been offering acoustic design consulting I have come to the conclusion that there are three different levels available to the end consumer. Each level offers a certain quality and cost level. By quality I am referring to how good the room sounds at the end of whatever design process is undertaken.

I've summarized this relationship in the chart that follows.

  • Quality refers to the sound quality improvement realized from acoustic design and treatment with 0 being no improvement and 100 being substantial improvement.
  • Price refers to the cost of the combined services plus acoustic treatment

You will see by following the red line (the 'value curve') that a good level of quality is realized at quite low cost from the acoustic treatment companies. As the curve enters the second level, where the new-breed of acoustical designers operate a small cost increase leads to a significant increase in quality. At the top you enter the realm of the specialist design companies. There are still quality gains to be had but they come at significant cost.
